TIME -RE CORDER.

Application filed May 23, 1906. iserial No.-318 ;3,1-1.

To all whom it may ctr/teem:

Be it lrn'own that 1, Errors 'WinnnLn iii-nrtm Ewan-rue; a subjectof the German Emperor, residing at CasseL'Germany, haveinventedn new and useful Improvement in Time-Recorders, of which the foll owing is *anpecifmatio'n.

' This 1 invention relates to that class of time recorders'in whicha strip or ribbon'o'f'paper is moved by 'a clock work past an opening through whichthe *ribbonor strip is exposed for writing the name of the person to be controlledupon-the-same,-the opening being normally closed by a cover which is withdrawn to uncover the opening -when the name is to be written upon the strip-and returned to its closed position when the signature has been made.

The object of this invention is to provide convenient means for stopping the movement of the paper strip by the opening movement of the cover and releasing the strip by closing the cover.

In the accompanying drawings: Figure 1 is a sectional side elevation of a time recorder provided with my improvement. Fig. 2 is a sectional elevation showing parts of the mechanism on an enlarged scale, the clamping plate being shown released. Fig. 3 is a similar vertical section through the clamping device, showing the clamping plate pressed against the strip. Fig. 4 is a section through the clamping device in line 44, Fig. 2. Figs. 5 and 6 are front and rear views of the clamping device. Fig. 7 is a fragmentary face view of the recording strip.

Like letters of reference refer to like parts in the several figures.

A represents the case of the apparatus provided with a clock mechanism B which operates the feeding roll 0 by which the paper strip D is propelled in an upward direction from the lower roll E from which the strip is unwound. The strip is delivered from the upper roll G into the lower portion of the case. The strip of paper is provided with divisions or marks arranged at such intervals and in such manner as may be required for effecting the desired control by recording the name of the watchman, workman or other person upon the same. This strip passes through a clamping device which is arranged on the front side of the casing, preferably in an inclined position for conveniently writing the name upon the part "of the strip'whioh is exposed 'through'the iopening .of the clamping device. The latter-comprisesiaframe F having a passagefthrou'glrwhichtheistripipasses upwardly-andwhich has inits front portion an opening g through which Ia part of the strip 'is "exposed for writing upon :the same. This opening is covered bya slidingcoverrH which moves in lateral ways h of the frame F and which is so constructed thatthe opening of the'frame-canbe uncovered bymoving the cover to-one side. The-cover=is preferably provided with an opening 11 which corresponds in sizeand formwiththe opening 9 of the frame, while the -'solid portion of the cover H covers the opening g of the frame when the cover is closed. By moving the cover to one side the opening i of the cover is placed over the opening 9 of the frame and the strip is exposed through these openings.

The frame F is provided with a clamp K which is arranged in the strip passage f of the frame F against the rear wall of the latter and which is movable toward and from the front wall of the frame. This clamp is operated by the sliding cover H, or otherwise so connected with the same that when the cover is closed the clamp lies adjacent to the rear wall of the frame, as represented in Figs. 2 and 4, and leaves the strip free to move through the passage f, while by 0 ening the cover the clamp is ressed toward the front side of the frame an presses the strip against the same, as shown in Fig. 3, thereby stopping the movement of the strip and holding the latter stationary while the cover remains 0 en, thus permitting the signature to be p aced conveniently and correctly upon the strip. The clamp consists, preferably, of a flexible or elastic plate of sheet metal which is secured at one end to the frame F and which is pressed forwardly by a projection or incline Z on the rear side of the cover H of the clamping device. This plate also serves as a convenient support or backing for the part of the strip on which the signature is placed. Upon closing the cover the clamp ing plate releases the strip and the latter resumes its movement under the action of the clock mechanism.

The time at which the name was written upon the strip of paper is indicated by the marks or divisions arranged upon the strip or ascertained by a separate scale with which the strip can be compared. For illustration, if the Watchman is required to enter his name upon the recording strip every half hour during his period of Work, the marks or divisions on the strip can be so arranged as to'repre-' sent intervals of thirty minutes each, as indicated in Fig. 7. The time occupied in lacing a signature upon the stri ordinarily oes not exceed afeW seconds an this period, during which the strip is held against movement, is so small that the ordinary clearance of the teeth in the driving gear is sufficient to prevent the strip from getting out of register With the clock Work. Even if the strip should remain clamped for an excessive length of time it cannot be torn by the action of the clock Work because the strip is driven by frictional contact and is capable of slipping on its driving wheel if prevented from moving with the same.

I claim as my invention:

1. In a time recorder, the combination of a frame provided with a passage for the recording strip and with an opening through which the strip is exposed, a movable cover for said opening, a movable clamping plate attached to said frame and having its free portion arranged opposite said opening and adapted to be pressed against the rear side of the recording strip and form a clamp and back support therefor, and means on said cover for pressing said plate against the strip by opening the cover and releasing the plate from the strip by closing the cover, substantially as set forth.

2. In a time recorder, the combination of a frame provided with a passage for the recording strip and With an opening through which the strip is exposed, a sliding cover for said opening,- a flexible clamping plate attached to said frame and having its free portion arranged opposite said opening and adapted to be pressed against the rear side of the recording strip, and a projection on the sliding cover adapted to engage said plate and press the same a ainst the strip by opening the cover and releasing the plate from the strip by closing the cover, substantially as set forth.

Witness my hand this 5th day of May, 1906.
